The battery finally died around 7 AM on Sunday, after lasting for nearly 38 hours on a single charge, with 4G LTE on and with the WiFi radio on but not used. The only other smartphone I’ve used that came close to lasting this long was the HTC ThunderBolt with a huge extended battery and a plethora of battery tweaks.

The Droid RAZR MAXX has great battery life right out of the box, no tweaks needed. If you do want to take the battery farther, you can use the included smart actions and other battery life tips and turn yourself into a smartphone battery hyper-miler, but for most users the battery is perfect right out of the box.

The Droid RAZR MAXX lasted a day and a half on a single charge.

RAZR MAXX - Thin and light with an all day battery.

The Droid RAZR MAXX shown above was taken out of the box and used in the following way during my battery test.

One Gmail account connected, averaging near 100 emails a day (not including spam)

One Twitter account connected and updating every hour (default for Twitter app)

Brightness set at Automatic (default setting)

Google Talk used heavily

1 – 1.5 hours of phone calls

A couple hours of web browsing.

45 texts sent

Light music listening

No gaming

This may not be your specific smartphone usage, but it is representative of many users and readers I have talked to over the past year. I am confident that I can get through a full day of my heavy use, which will be tested this week.

I’ve argued that longer 4G LTE battery life is possible without destroying the looks and pocketability of a phone, and Motorola has proven that you can have a thin 4G LTE phone with long battery life.

There’s not a lot phones that outpower the RAZR MAXX. the GNEX has a cheap build, poor reception, and the SAME processor as the RAZR- not to mention battery life is miserable like all other 4G devices, not including the MAXX.

I wish there was dislike buttons. Display is very clear, crisp and bright. The MOTOblur launcher can be replaced by smooth and feature rich 3rd party launchers through the market, same with dialer and just about every other “interface” aspect of the phone.

Why does everyone complain about the interface? Isn’t the beauty of having an android the fact that you can customize it in so many different ways? It took me 30 seconds to download a 3rd party launcher app, and 20 minutes of playing around to configure it in a way that looked great, and was extremely smooth/fast.

I am shocked by all these people who say the battery life on the Maxx is so great. I am an average cell phone user … and I get a little over 1 day charge on the Razr Maxx doing much less than the person who wrote this article. I took my phone back to verizon thinking I might have a defective battery, and the tech person said it seems normal. A lot of the ‘reviews’ which claim heavy usage 1.5 day battery life … or the incredibly false story of the ‘3 day Maxx business trip’ are bogus from what my actual Droid Razr Maxx gets.

I recently got a razzr maxx but many of my friends have the iphone and heres what I see in comparison. The iphone like most apple products is king of user-friendliness..thats its bread and butter. I mean everything seems so easy to do! Android has a lot of potential..meaning you have to be into programming and optimizing. Android is tough for someone like me with little patience for that..simple things are difficult at times. That being said I got the razzr max for its exceptional battery and reception(I now live somewhere very rural and get reception unheard of with other phones). Also the obvious size and sleekness is terrific, I dont know its even in my pocket a lot of times. For those reasons along I am very happy with it. Also I will be looking forward to that upgrade for Ice Cream Sandwich..
